We IBM Team is working with 3scale to get it running on on PowerPC and z/OS.
We hit a snag, whilst building System Container Image ( https://pkgs.devel.redhat.com/cgit/containers/3scale-toolbox/log/?h=private-ppc64le )we observe despite any condition build always pulls nokogiri-1.11.7-x86_64-linux.gem irrespective of architecture.

However, we would like add a "gem" nokogiri-1.11.7.gem to https://origin-repository.jboss.org/nexus/content/groups/rubygems_store/gems/n/ 

Can you help us on how we can publish a gem to the internal repository?
